Comparative cytogenetic and morpho-anatomical study among diploids and polyploids of Solanum elaeagnifolium (Solanaceae)
Background and aims: Solanum elaeagnifolium, morphologically variable, multiplies sexually and asexually and is invasive worldwide. Its range of origin and how it spread outside of it is unknown. In Argentina there are natural diploid, tetraploid and hexaploid populations. It presents three clearly...

Background and aims: Solanum elaeagnifolium, morphologically variable, multiplies sexually and asexually and is invasive worldwide. Its range of origin and how it spread outside of it is unknown. In Argentina there are natural diploid, tetraploid and hexaploid populations. It presents three clearly separated genetic lineages, two in South America with polyploid populations and a third with only diploids in North America and invaded areas. Our aim is to detect relationships among ploidy levels, lineages and provenance with morphological features of the plants and climatic variables.
M&M: Chromosomal preparations and measurements of epidermal, floral and seed features were made in 2x, 4x and 6x individuals from different lineages and geographic origin. The mean values obtained were compared by statistical tests and the global similarity assessed by multivariate analyses.
Results: Only number of stomata and seed mass were significantly different between ploidy levels: the tetraploid cytotype has fewer stomata and heavier seeds. The remaining morphoanatomical variables contribute to the global differentiation of cytotypes, although it was not found that the means varied proportionally with increasing ploidy. Mean annual rainfall contributes to the separation of cytotypes, the western distribution of tetraploids coinciding with the arid diagonal in Argentina.
Conclusions: The differences in the tetraploid cannot be attributed to a polyploidization effect. The global pattern of data could be explained by multiple independent origins of polyploidy, phenotypic plasticity, and environmental pressures (temperature, rainfall, different pollinator assemblages). |

Introducción y objetivos: Solanum elaeagnifolium, morfológicamente variable, se multiplica sexual- y asexualmente y es invasora en distintas partes del mundo. Se desconoce su rango de origen y como se propagó fuera de él. En Argentina existen poblaciones naturales diploides, tetraploides y hexaploides. Presenta tres linajes genéticos claramente distanciados, dos en Sudamérica con poblaciones poliploides y un tercero solo con diploides en América del Norte y áreas invadidas. Nuestro objetivo es detectar relaciones entre nivel de ploidía, linaje y procedencia con características morfológicas de las plantas y variables climáticas. M&M: Se realizaron preparados cromosómicos y mediciones de caracteres de epidermis, flor y semilla, en individuos 2x, 4x y 6x de diferente linaje y origen geográfico. Se compararon los valores medios obtenidos mediantes tests estadísticos y la similitud global se evaluó mediante análisis multivariados. Resultados: Únicamente número de estomas y masa de semillas resultaron significativamente diferentes entre niveles de ploidía: el citotipo tetraploide, presenta menor número de estomas y semillas más pesadas. Las restantes variables morfoanatómicas contribuyen a la diferenciación global de los citotipos, aunque no se comprobó que las medias variaran proporcionalmente con el aumento de ploidía. La precipitación media anual contribuye a la discriminación entre citotipos, coincidiendo la distribución occidental de los tetraploides con la diagonal árida en Argentina. Conclusiones: Las diferencias en el tetraploide no pueden atribuirse a un efecto de la poliploidización. El patrón global de datos podría explicarse por múltiples orígenes independientes de la poliploidía, plasticidad fenotípica y presiones del ambiente (temperatura, precipitaciones, distintos ensambles de polinizadores).
